SPRING.

SPECIFICATION forming part of Letters Patent No. 746,299, dated December 8, 1903.

Application filed March 24,1902- Serial No. 99,780. (No model.) it

To all whom it may concern Beit known that I, FRANK P." DAROY, a

city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain-new and useful Improvements in Springs, of which the following is a specification.

, This invention relates to improvements in springs for cushions or the like.

The objects of this invent-ion are, first, to provide an improved spring for cushions or the like in which the parts shall be securely retained in position in a simple and effective manner; second, to provide an improved spring for cushions or the like in which the parts may be quickly and easily assembled and in which the parts are simple and economical to manufacture; third, toprovide an improved spring for cushions orthe like which can be shipped in the knockdown and be quickly and easily assembled by the user.

Further objects will definitely appear in the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined, andpointed out the claims. v

A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a top plan view-of a structure embodying the features of myinvention, portions being shown in dotted lines to show the relation of the parts. Fig- 2 is a detail cross-sectional view taken on aline 2 2 of Fig.

1, portions being shown in full lines to show the details of construction. Fig. 3 is an enlarged detail view showing the manner of connecting the spiral springs B to the crossbars 0. Fig. 4 is adetailcross-sectional view taken on lines 44 of Figs. 3 and 5. Fig. 5 is a detail longitudinal sectional .view taken on line 5 5 of Figs. 3 and 4. Fig. 6 is a detail cross-sectional view showing in dotted lines the position the parts assume in uniting the same. Fig. 7 is a detail view of the end of one of the cross-bars C.

In the-drawings all of the sectional'views are taken looking in the direction of the little arrows at the ends of the sectional lines,

and similar letters of reference refer to the similar parts throughout the several views. Referring to the lettered parts of the drawings, A represents the wood frame of a cushion,which may be of any desired size or shape,

that illustrated being adapted for use in-a carriage.

B. represents spiral springs, which are of the usual-construction. I

Cross bars or rods 0 are provided, and these are formed with loops 0 C" at inter.- vals to form hooks for holding the spiral springs. The loops 0" arepreferably of some distance apart, as at G, as this serves to hold" the spring more rigidly in position. The rod is stifiened by the treatment. 1 A pair of these cross bars or rods 0 are provided for each series of springs and are hooked into the bottom coil of the spring in opposite directions, so that when the bars are fastened to the frame A the ends are-bent into hooks, which are driven into the frame. I prefer to form ,barbs on the ends to assist in retaining the same. If it isdesirable, after plac'- ing the springs on'the cross-bars theloops may bebent down so that it'will be impossible to remove the springs,alth-ough this is not an essential, as when the same are assembled and secured to the frame the springs are securely retained'in position, and it is impossible to remove them without loosening one of the cross-bars. I prefer to form the hooks in the cross-bars as illustrated. I am aware that there are variousways of forming books or loops on the cross-bars, how over, which would form practical structures. The hooks, however, must be considerably separated to form a base for the attachment of thebase or bottom coil of the springs, so

that the spring will not yield and tip overin i the direction of the length of the rod and will be retained on the top of thebase in all directions, and thus effectively supported so that it cannot be displaced in. use. This is of the greatest importance in these cushion structures as it saves the tying of the tops of the springs together and yetretains the springs absolutely inv one position, so that they will notflby vibration wear into the cushion and so that they will always be in the correct and proper position to secure the best results; I

believe,'however, that the form illustrated is the simplest to construct and the meet satisfactory in use, although I am aware that it is capable of considerable structural variations without departing from my invention.

The cross-bars C might be easily seen red to the frame A by other means than those illustrated. The means illustrated on account of its economy and simplicity and the rapidity with which the parts may be assembled is very superior. I

Other variations in structural details will readily appear to those skilled in the art to which my invention appertains.

Having thus-described my invention, What Iclairn as new, and desire to secure by Letters Patent, is-

1. In combination, a frame, a plurality of parallel supporting-wires arranged in pairs, a row of springs supported by each pairof wires independently of the adjoining springs, said wires passing beneath the lower coils within the periphery thereof and contacting with each spring at four widely-separated points, said Wires having hook-shaped bends' engaging the lower coils of the spring intermediate of the points of contact, substantially-as described. V a

2. In a spring structure the combination of a suitable frame: coiled springs: pairs ofindependent parallel supporting-reds, the opteases posits ends of which are suitably secured to said frame, the said rods having hooks which are formed intermediate the ends'thereof, and extended into and engaging the bottom coils of said springs, thereby retaining them in position, as specified.

3. In aspring structure, the combination of a suitable'frame; coiled springs: a series of independent pairs of parallelsupporting-rods, the opposite ends of which are suitably secured to the said frame, the said pairs of rods having hooks formed intermediate the ends of said rods extending into and engaging the bottom coils of said springs and retain them in position, as specified.

4. In a spring strncturea snitablesupporting-i'rame; a coiled spring; a pair of supporting-rods extending beneath the bottom coil of said spring and having upwardly and outwardly extending hooks formed intermediate of their length engaging the bottom coil of saidspring to form an independent support for said spring, as specified.

In witness whereof I have hereunto set my hand and seal in the presence of two Witnesses.
